It's pretty simple.  You use tilestache's URL template provider to proxy
requests to the REST server.  It works as long as the server supports the
web mercator projection, which might be under any of the SRIDs 900913,
102113, 102100, 3785, or 3857.  (The last is the current official code
from EPSG.)  Here's what I use for Anne Arundel County's orthoimagery:

{
  "layers": {
    "AAOrtho2010": {
      "provider": {
        "name": "url template",
        "template": "http://gis-world.aacounty.org/ArcGIS/rest/services/Ortho2010/MapServer/export?f=image&bboxSR=102113&bbox=$xmin,$ymin,$xmax,$ymax&size=$width,$height&format=png24"
      },
      "preview": {
        "lat": 38.974,
        "lon": -76.595,
        "zoom": 10
      }
    }
  }
}

For their vector-based data, I add `transparent=true` so I can overlay it
on aerial imagery:

    "AABasemap": {
      "provider": {
        "name": "url template",
        "template": "http://gis-world.aacounty.org/ArcGIS/rest/services/Basemap/MapServer/export?f=image&bboxSR=102113&imageSR=102113&transparent=true&bbox=$xmin,$ymin,$xmax,$ymax&size=$width,$height&format=png"
      },
    }
